Had to find a parking space for our Promaster van due to HOA covenants and regulations, so we started looking. Ron was very helpful with the process, and we are happy with the facilities. The parking space is reasonably priced and easy to access. Everything looks well protected and secure. Thanks Ron… being nice and helpful matters. 23April_David called to follow up on our experience of storing our van with Morningstar. Ron’s excellent way of treating people must have influenced David because he was very nice and sincere when he called us. I know this is just a place to store our personal items; however, it’s important to get this right. The entire process has been well above par in our opinion. Thanks again Ron and David for a job well done!

Tammy at the 609 Old Trolley Road location went above and beyond for me! She provided detailed instructions on how to add a guest to the Extra Space app AND an annotated map of the site itself to help the tow-truck driver—and the local person meeting him—navigate to the unit. She's one of a kind—she remained friendly and personable while patiently answering my barrage of questions! (I live out of state and conducted the transaction by phone.) I highly recommend this location just on the basis of my interaction with her.
